When I started at Lincoln in Feb. 1959, the student body
of 3000+, had seven black students. They were well treated.
Most of us hadn't been around blacks before then. By the time I graduated in Jan. 1962, there was 450 blacks at Lincoln. Busing had begun during the previous three years.
A small segment of these new students, were unruly, trouble makers. They would take over the cafeteria during the lunch
hour, playing their music loudly, dancing on the tables, etc.
Remember this was a small percentage of the new students, but they didn't make it any easier for the rest of them to be accepted.
